Homework Equations
The Attempt at a Solution
I can't understand the question.
Is the initial velocity of the ball when it is dropped=0? or is it 7m/s.
What value should I take for g? Should I take g= 9.8 m/s[itex]^2[/itex]?
Please help me. I assumed ball is dropped from 60 m height with initial velocity=0 and a=g=9.8 m/s[itex]^2[/itex]. But it gives wrong answer. What is the concept of this question? How to solve it?
